Merge bitcoin/bitcoin#20457: util: Make Parse{Int,UInt}{32,64} use locale independent std::from_chars(…) (C++17) instead of locale dependent strto{l,ll,ul,ull}
4747db876154ddd828c03d9eda10ecf8b25d8dc8 util: Introduce ToIntegral<T>(const std::string&) for locale independent parsing using std::from_chars(…) (C++17) (practicalswift)
Pull request description:
Make `Parse{Int,UInt}{32,64}` use locale independent `std::from_chars(…)` (C++17) instead of locale dependent `strto{l,ll,ul,ull}`.
[About `std::from_chars`](https://en.cppreference.com/w/cpp/utility/from_chars): _"Unlike other parsing functions in C++ and C libraries, `std::from_chars` is locale-independent, non-allocating, and non-throwing."_
